COYNE AND SAMUEL F. ROBIDOUE, BOTHVOFQPROVIDENCE, RHODE ISLAND canin Application filed January 24, 1929. Serial N'o. 334,813.

This invention relates to a block link chain for use as a'bracelet, necklace and similar articles for personal use and adornment and is an improvement on copending application Serial N o. 263,185, filed March 20, 1928; and has for its object to flexibly connect a series of block links in a simple and efficient man- A" further object of the invention is the method of'forming the bracelet, necklace or the like by casting the block links to a strip of mesh fabric so that one part of the mesh fabric is secured to one block link and another part which is movable relative to the first part is secured`to the next adjacent block link to flexibly connect thek links together in series. Y

With these and other objects in view, the invention consists of certain novel features of construction, as Will ybe more fully described, and particularly pointed out in the appended claims.

' In the accompanying drawings:

Fig. 1 is a top plan view of the bracelet formed of my improved construction.

Fig. 2 is a bottom view of a lportion thereof.

Fig. 3 is a top plan View of the mesh fabric illustrated somewhat diagrammatically, which is used'as a connecting element for the block links. I

Fig. 4 is a sectional view through the block Y links and their connecting mesh fabric.

Fig. 5 is a fragmental top View of the mold which is used for casting the bracelet with the top or cover removed. Y

Fig. 6 is a sectional view of the mold with the cover in place and also the mesh fabric strip therein before the metal is poured into the different compartments.-

Fig. 7 is a sectional view of the mold withV the bracelet positioned therein and the material filling the gate-,ofthe mold.

` Fig. 8 is a sectional view on line 8,-8 of Fig. Y Y

Fig. 9 is a sectional view of a modification ofthe bracelet showing the mesh connecting vportion as positioned along the bottom of the links. l

It is found in the manufacture of a bracelet of this cast block link construction that the use of a mesh 'strip for vconnecting the blocklinks together is an :improvement from the standpoint of durability and alinement of the links, and also is more efficient to manufacture than the provision-of a pair of spaced chain Ylinks as provided in the abovementioned application; and the following is a detailed description of the present method and article formed by connecting the block links together'with mesh fabric. c

Vith. reference tothe drawings, 10 designates the mold which is provided with a plurality of compartments 11 formed by separating partitions 12, each of Which has a. notch 13 therein, clearly illustrated in Figs. 5 and 8, `to receive a strip of mesh fabric 14 as is indicated in Fig. 6, the partition extending to a height greater than the strip of mesh fabric at the point l5 at either side thereof.` Each of these compartment partitions is'inclined on either sideto form bev-- eled ends 18 and 19 on the block links 20 for properly shaping the links so as to permit flexibility of the chain about the arm of the wearer. The mold is also provided with a trough or gate 2l with channels 22leading to each of the compartments through which the metal 23 inthe molten state flows to fill eachofv the compartmentsll and provide a pluralityof blocks 20, as illustrated in F ig.v 4. As ythe metal flows into each of the compartlments it casts the mesh fabric 14 therein, firmly imbedding the' same in each of the block vlinks but leaving a sufficient portion ofthe mesh fabric between each of the links sovthat flexibility of the chain is permitted, the arrangement being such that one relatively movable part of the mesh fabric is cast in one of the links While another part of the mesh fabric movable relatively to the ormed ina very thin Web between thelinks which may be easily broken upon removing the bracelet from the inold to allowr the re quired flexibility of the chain. Y l In Fig. 9 I have illustrated the Inesh fabricll as extending` along tothe bottoni of the links 28 which maybe securedto the block links 28 by casting in a similar manner yto .that above Inentioned.Y

It .will be obvious .t at iti of the chain als short portions may be pro# vided between each of the block links to con,- nect them'together. The metal which Iv use for the block links is ofso-,called White metal,

alloy whilethe mold is bronze, as isV de sribed in the abo've lsaid application.
